Is it possible to get DMT released through your body via meditation?

I just meditated i was in deep meditation when i get this rush of feelings, my legs kinda went numb, i saw a light through my vision it was a wave of this rush of kind of euphoria sensation. I felt like i was being rushed up, and up it was crazy. Could this be a conscious natural release of DMT? And other then the light of say these patterns of light blue it would start up vanish and start up again.
